I would try the 'real' Big List...which is NOT a yahoo group. It is run by the St. John's Listserve. Directions for joining are at:
www.guatadopt.com
If you are a member of the yahoo listserve you should be getting 20-50 messages per day from that group...simply hit reply to a message, change the title, ask for feedback and hit send...hopefully someone will answer.
Good Luck!
